there lot of questions storing time series cassandra, no 1 fits our question, because assume fixed data source , known column names. about our problem: we're developing stream data engine, can connect different data sources, engine receives data continuous streams. so, have example 2 data sources called energy , weather . each incoming stream (or data source) has own unique key , own schema, e.g.: source id 1 schema energy may has stream: timestamp | volts | amps | watts | state 1467795743173 | 210.4 | 2.3 | 290 | "up" 1467795744173 | 212.1 | 2.1 | 287 | "up" 1467795745173 | 213.1 | 2.2 | 242 | "up" ... source id 2 schema weather may has stream: ts | condition | temp 1467795740632 | "cloudy" | 33.1 1467795741381 | "cloudy" | 33.4 ... now want give possibility store streams cassandra, can used later "replay" recorded stream, fetch historic results (e.g. analytics) , enrich/join incoming streams spec

is possible check if mysql server has ssl connections enabled without logging in, assuming have port , ip? theoretically possible that, requires understanding of mysql's own protocol , advanced socket programming. as part of initial handshake process, mysql server sends initial handshake packet . part of capability flags mysql server sets client_ssl flag if supports ssl : the ssl support announced in initial handshake packet sent server via client_ssl , enabled if client returns same capability. this packet sent before authentication, not have authenticate determine if mysql server support ssl. however, in various mysql apis cannot ask initial handshake packet sent. in c api have mysql_real_connect() connect server immediately. so, need write own code initiate connection mysql server, process server's initial handshake packet, determine if supports ssl , close connection.
